AIR-CIRGULATOR.

Specification of Letters Patent.

Application filed July 16, 1909.

Patented July 25, 1911.

Serial No. 508,040.

culators, of which the following is a specification.

This invention relates to an air circulating devicezcomprising astandard or pedestal having a superposed top or deflector and havingmounted thereon an electromotor and fan, and being fitted with lampsetc., all as hereinafter more particularly de scribed,

The invention illustrated in the accompanying drawing the figure ofwhich is a part elevation part vertical section.

As shown, the said device comprises a hollow standard A of suitable,preferably ornamental, des gn, and preferably composed of porcelain,china, delf, or other suitable material: the said standard beingprovided with a base (4 adapted to rest on a table or the like, andleaving an opening or openings at u for air to enter at the underside ofthe standard. The standard is also provided with perforations-oropenings for the passage of additional air. In said hollow standard iscontained an electromotor B of which the spindle carries the fan wheel Cand is disposed vertically as shown and has a bearing in a bracket D.

The fan wheel (3 is built substantially according to the constructiondescribed in the specification of Letters Patent No. 935,114 beingcomposed of two sets of blades, the blades being preferably ratherflatter than in the fan wheel described in the prior specification, andbeing :aused to run with their convex faces acting on the air, andserving to circulate through a room air passing up through the hollowstandard and between the arms of the lower bracket 1), and air enteringat the" top bet-ween the arms of an upper bracket E which latti' 'restson a base i that also serves to support a delicctor G preferablycomposed of porcelain, china or delt, and which base F is supported fromthe standard A by, means of coluu'ins or pillars ll, preferably composedof metal.

' t will be seen that the fan runner has two inlet openings. the lowerinlet opening registering with the top'of the standard and the upperinlet. opening registering with the center opening of the deflector.

The columns or pillars H are hollow, cables being led through the sameto supply current to electric lamps J hung from the deflector G.

A flower vase K of glass or other suitable material is carried by theupper bracket E.

The arrangement is such that the fan will circulate air from the surfaceof a table or the like and air from above a table or the like,deflecting the air in a continuous horizontal stream, gently andnoiselessly, the volume being distributed all around the table or thelike;

Having now described my invention what I claim and desire to secure byLetters Patent of the United States is 1. An air circulator comprising ahollow standard open at the upper end; a lower bracket having a centraldepressed portion and having an annular base resting on said standard; amotor secured to said depressed portion and depending in said standard,the shaft of the motor extending centrally upwardly through the bracket;pillars on said annular base; an upper bracket also having an annularbase resting on the pillars; a double fan runner on said shaft betweensaid annular bases, said fan runner being fitted with tapering bladesaffording two intake eyes, registering with said bases respectively; anda deflector having central opening received on the base of the upperbracket.

2. 1 11 air circulator comprising a hollow standard having an open upperend surrounded by an annular groove, said standard being also providedwith lateral open-- ings in its lower part; a lower bracket having aring engaging in said groove, the bracket also having a depressedcentral. portion; a motor depending in said standard and secured to saiddepressed portion, the shaft of the motor extending centrally,vertically through the depressed portion; an open fan on said shaft, andcomprising blades and an upper and a lowc ring, the lower ringregistering with the ring of the lower bracket; hollow pillars restingon said ring of the lower bracket and extending to about the height ofthe tan; an upper bracket having an annular base resting on saidpillars; and an annular duller-tor having a groove receiving said base.

3. An air cireulator comprising a hollow standard having an open upperend surrounded by an anntnar groove, said standings in its lower part; alower bracket aving a ring engaging in said groove, 'the v bracket alsohaving a depressed central ortion, a motor depending in said stan ardand secured to said depressed portion, the shaft of the motor extendingcentrally, vertically through the depressed portion; an open fan on saidshaft, and comprising blades and an upper and a lower ring, the lowerring registering with the ring of the lower bracket; hollow pillarsresting on said ring of the lower bracket and extending to about theheight of the fan; an upper bracket having an annular base; restingio'ii' said pillars; an annular'deflector having a groove receiving saidbase; la'rnps hanglng at the outer edge of the deflebtors; andconductors passing up through the hollow pillars to the lamps.
